Question

Balanced equations for "the extraction of copper from copper pyrites by self-reduction." is :$C{u}_{2}S+2C{u}_{2}O\to 6Cu+S{o}_2$.

If the given statement is true enter 1 else 0.

Answer 1

This is the balanced equations for the extraction of copper from copper pyrites by self-reduction.
Roasting:
$2CuFe{S}_2+O_2\stackrel{\Delta }{\to }C{u}_{2}S+2FeS+S{O}_2$
$2C{u}_{2}S+3O_2\to 2C{u}_{2}O+3S{O}_2$
$FeS+3O_2\to 2FeO+2S{O}_2$
Smelting:
$FeO+Si{O}_2\to FeSi{O}_3$ (slag)
$C{u}_{2}O+FeS\to C{u}_{2}S+FeO$
Bessemerization:
Self-reduction
$C{u}_{2}S+2C{u}_{2}O\to 6Cu+S{O}_2$
